• the present invention relates to a looped fabric and more in particular to a terry.
• the present invention also relates to the improvement of the technical and external appearance and characteristics of the obtained terry.
• fabrics having loops such as terry from which e.g. bath towels are made, consist of loops that are drawn from a supplementary warp thread or weft thread and fastened on the fabric or ground layer.
• fabrics are also referred to as looped fabrics, whereby the loops are formed by the warp or the weft.
• Such fabrics are respectively also referred to as warp or weft looped fabrics.
• the ground fabric consists in general of a woven underlayer. Weave of the ground fabric may comprise, but is not limited to, a plain weave, a panama weave or a twill weave. The loops are most frequently made of cotton or another fibre.
• Such fibres and the underlayer to which the loops are fastened are not always biologically degradable.
• Besides cotton other fibres of natural or synthetic origin are known. More specifically, with regard to terry, cotton fibres are preferably used.
• the main characteristics of looped fabrics are determined by the loops which are generally, but not necessarily, provided on both sides of the ground fabric.
• the main purpose of such looped fabrics is their use as towel to dry the body. This implicates a great number of specific requirements, including good water absorption; a certain flexibility; an acceptable consistency of the loops; good stabilities: the towel should be resistant against washing at high temperatures, sunlight, etc.. ; the towels should satisfy certain dimensions that are requested by a customer.
• Looped fabrics are most frequently applied as cloths such as towels, bathrobes, but recently also more as a technical fabric for example in the application as walking socks. Looped fabrics also have other applications such as for floor mats (heavy structure) for bathrooms as well as for clothing.
